Vultures and honeybees

Vultures

Buechley and Sekercioglu introduce vultures, the supreme avian scavengers that now face multiple threats.

Temperature Regulation in Turkey Vultures

Temperature regulation by six Turkey Vultures (Cathartes aura) was studied at ambient temperatures (T,) from 11 to 40°C in a metabolic chamber. Within this range body temperature varied little, averaging 39.7”C, and the ratio of CO, production to 0, consumption averaged 0.76. The thermal-neutral zone (TNZ) extended from 26 to 40°C. Below 26°C evaporative water loss and the heat-transfer coeffic...

Honeybees and Tetracycline Resistance

Like animals and people, insects can serve as both collectors and disseminators of antibiotic resistance genes, as exquisitely demonstrated by a recent study (B. Tian, N. H. Fadhil, J. E. Powell, W. K. Kwong, and N. A. Moran, mBio 3[6]:e00377-12, doi:10.1128/mBio.00377-12, 2012). Notably, the relatively confined ecosystem of the honeybee gut demonstrates a large propensity for harboring a diver...

Honeybees and magnetoreception.

immune sera, polyclonal rabbit antibodies to human IL-1 f3, or anti-p20 ICE and protein A-agarose. After extensive washes, the adsorbed proteins were eluted by boiling the beads in SDS-PAGE sample buffer and analyzed by SDS-PAGE and autoradiography. 13. The ICE homologs and p35 were expressed in E coli under the control of the X pL promoter. ICH-1 (7) and CPP32o (8) contained a polyhistidine li...
